Query Related Records (Map Service\Layer)

Description

NoteNote:

This operation was added at 10.0.

The query related records operation is performed on a layer / table resource. The result of this operation is one or more featuresets grouped by source layer / table object IDs. Each featureset contains Feature objects including the values for the fields requested by the user. For related layers, if you request geometry information, the geometry of each feature is also returned in the featureset. For related tables, the featureset does not include geometries.

Also, each featureset contains an array of field information objects for fields requested in outFields parameter. See Layer/Table for details on fields.

NoteNote:

The domain's member is not included in field information objects returned with the response.

New in 10.5

New in 10.1

NoteNote:

All parameters related to geometry will be ignored when querying related tables.

You can provide arguments to the query related records operation as query parameters defined in the parameters table below.

Request Parameters

Parameter

Details

f

Description: The response format. The default response format is html.

Values: html | json | amf

objectIds

Description: The object IDs of this layer/table to be queried. Records related to these object IDs will be queried.

Syntax: objectIds=<objectId1>, <objectId2>

Example: objectIds=37, 462

relationshipId

Description: The ID of the relationship to be queried. The relationships that this layer/table participates in are included in the Layer / Table Resource response. Records in tables/layers corresponding to the related table/layer of the relationship are queried.

Example: relationshipId=4

outFields

Description: The list of fields from the related table/layer to be included in the returned featureset. This list is a comma delimited list of field names. If you specify the shape field in the list of return fields, it is ignored. To request geometry, set returnGeometry to true.

You can also specify the wildcard "*" as the value of this parameter. In this case, the results will include all the field values.

Example: outFields=AREANAME,ST,POP2000

Example (wildcard usage): outFields=*

definitionExpression

Description: The definition expression to be applied to the related table/layer. From the list of records that are related to the specified objectIds, only those records that conform to this expression will be returned.

Example: definitionExpression=POP2000 > 100000

returnGeometry

Description: If true, the featureset includes the geometry associated with each feature. The default is true.

NoteNote:

This parameter only applies to related layers. It will be ignored for related tables.

Values: true | false

maxAllowableOffset

//This option was added at 10.0.

Description: This option can be used to specify the maxAllowableOffset to be used for generalizing geometries returned by the query related records operation.

The maxAllowableOffset is in the units of the outSR. If outSR is not specified, the maxAllowableOffset is assumed to be in the unit of the spatial reference of the map.

Example: maxAllowableOffset=2

geometryPrecision

//This option was added at 10.1.

Description: This option can be used to specify the number of decimal places in the response geometries returned by the queryRelatedRecords operation. This applies to X and Y values only (not m- or z-values).

Example: geometryPrecision=3

historicMoment

This option was added at 10.5 and works with ArcGIS Server services only.

Description: The historic moment to query. This parameter applies only if the supportsQueryWithHistoricMoment property of the layers being queried is set to true. This setting is provided in the layer resource.

If historicMoment is not specified, the query will apply to the current features.

Syntax: historicMoment=<Epoch time in milliseconds>

Example: historicMoment=1199145600000

outSR

Description: The spatial reference of the returned geometry.

The spatial reference can be specified as either a well-known ID or as a spatial reference json object.

If outSR is not specified, the geometry is returned in the spatial reference of the map.

NoteNote:

This parameter ony applies to related layers. It will be ignored for related tables.

returnZ

/This option was added at 10.1.

Description: If true, Z values will be included in the results if the features have Z values. Otherwise, Z values are not returned. The default is false.

NoteNote:

This parameter only applies if returnGeometry is true.

returnM

/This option was added at 10.1.

Description: If true, M values will be included in the results if the features have M values. Otherwise, M values are not returned. The default is false.

NoteNote:

This parameter only applies if returnGeometry is true.

returnTrueCurves

This option was added at 10.5.

Description: Optional parameter that is false by default. When set to true, returns true curves in output geometries; otherwise, curves are converted to densified polylines or polygons.

Values: true | false

Example: trueCurveClient is true.

gdbVersion

/This option was added at 10.1.

Description: GeoDatabase version to query. This parameter applies only if hasVersionedData of the property of the service and isDataVersioned property of the layer(s) queried are true. If this is not specified, query will apply to published map's version.

Syntax: gdbVersion=<geodatabase version>

gdbVersion

Example: gdbVersion=sde.USER1

Example Usage

Example 1: Query related records.
